Hugh Jackman, Shaq play 'Phone Booth' on Fallon

It's one of Fallon's more harebrained games—stuffing celebrities inside phone booths, asking them trivia questions, and then squeezing in more celebrities when they answer incorrectly.

And on Monday night's show, Jimmy had the perfect guest to go head-to-head with Hugh Jackman in "Phone Booth:" Shaquille O'Neal, whose 7'1" frame could barely fit inside the booth before miscellaneous guests started to join him inside.

But oh, did they join him inside.

Shaq got Alex Trebec.

Who hilariously started petting his very expensive suit.

While Hugh got a Blue Man.

Who put out a cry for help the only way he knew how.

And by the time the Property Brothers and the Mets mascot had to join Shaq's booth, the situation was dire.

Sorry, Mr. Met!
